1. When I was at school this was a generic term meaning "to pair off with", usually used at a party or other event designed specifically for pre-pubescent pre-sexual encounters. Means anything from a kiss to "going all the way"

2. However my other half thinks it means specifically "to have sex with" at the same event that you meet the person.

1. Oh my God! You'll never believe who Sally got off with at Dave's party last night!!

2. I see you used all the condoms up, you must have got off with Dave last night then?

when you go to a party and you got so many dances that your penis and the zipper of your jeans become one or in a female's case when her lower back hurts or when she looks like she just hopped out of the pool.It just means to enjoy yourself.......or to masturbate lols

Yo I danced with almost every girl in the party.I get off at every party we go to.

The opposite of a come on, a get off is a series of social cues and body language used to discourage an unattractive or otherwise undesirable suitor. Get offs are typically used by young females in clubs and may include activities such as clustering in large groups to avoid detection, hugging or otherwise feigning interest in friends (or, in desperate situations, complete strangers who seem friendly), disappearing off to the toilets for very long periods of time, talking loudly about old boyfriends, studiously avoiding eye contact and, as a last resort, telling said suitor to fuck off. These signals may be misinterpetted by a particularly verenthusiastic or idiotc suitor, at which point the ancient technique of the bitch slap comes into play.
Variants include geddoff, getoff and getafuckoff.

Guy1: Did you see that? Dude, she is so giving me the come on.
Guy2: What, by giving you the finger?
Guy1: I guess that's a get off, then.
